## Description

Product description 111SKIN Bio Cellulose Masks Made from coconut membrane. 500x finer than regular sheet masks. Ingredients will penetrate deeper. Use Bio Cellulose for a deeper treatment providing intensive nourishment. Great for damaged, dehydrated and inflamed skin. Application Apply the middle Bio Cellulose layer to clean, dry skin. Wear for 20 minutes. Use up to three times per week and for longer durations when extra hydration is needed.

Review: Indulgence - I'm a huge fan of 111Skin and everything they put out. They've got something for everyone, and the line was developed for people healing post surgery - those who couldn't tolerate the typically harsh products we have. That being said, you're obviously not going to notice anything magical from one use of this mask, unless you count radiance and supple dewey hydration as magical (I know that some of us do). This is a luxury mask that I cannot afford to use up to 3x weekly as directed, but an indulgence every once in a while is always sweet. If I were able to use this as often as they say to, I think I'd notice a difference in my skin. With my one and done use i still like what I see (or rather, what I mostly FEEL).
Review: Not their best - I’ve purchased other 111 Skin masks and love them. This one not so much. Being one piece it’s hard to get good placement. It’s good for moisture but their other masks deliver those results and are better for placement.

Yummy for the face. Very moisturizing. But very expensive.
